Inline Method
A method's body is just as clear as its name.
Put the method's body into the body of its callers and remove the method.
int getRating() {
return (moreThanFiveLateDeliveries()) ? 2 : 1;
}
boolean moreThanFiveLateDeliveries() {
return _numberOfLateDeliveries > 5;
}

int getRating() {
return (_numberOfLateDeliveries > 5) ? 2 : 1;
}
